This user guide supports the evaluation kit for the FAN6602R. It should be used in

conjunction with the FAN6602R datasheets as well as Fairchild’s application notes and

technical support team. Please visit Fairchild’s website at https://www.fairchildsemi.com/

1. Introduction

This document is an engineering report describing a 40 W power supply using the

FAN6602R, which is targeted for notebook adapters. It also describes the simple, low

cost and high performance reference design evaluation board.

The operating current in the FAN6602R is as small as 3 mA. The small operating current

results in higher efficiency and reduces the VDD hold-up capacitance requirement. Once

the FAN6602R enters deep-green mode, the operating current is reduce to 0.6 mA, thus

assisting the power supply to easily meet the power conservation.

By using the FAN6602R, an adapter can be implemented with fewest external

components and minimized cost.

ANTI-COUNTERFEITING POLICY

Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support.

Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts.

Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts.

Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise.
